I get the point but a lot of the NPC Story characters are quite unique, they have armor we dont have, but the general design of them (face/hair) yes is pretty much identical to every other char, there are i think just 2 different types of people, one is the old man and i dont remember other.

But you listed memorable characters as all being some significant main character like the guy from rank 46, i dont remember his name but he was completely unique and stands on the same shelf as the ones you suggest, where as the 4 others dont so much, they're not in the story much.

I think we will see a lot more uniquness though, like you want what you saw in XI i assume? Everyone remembers Lion XD or the Kid from COP,
